Fig. 2v is a View similar to Fig L 1, `showing ane other forni of the invention. i v y f Fig. 3; is an enlarged ragrnentary'elevatioll .of ene Qi the .faces 0f, a, radiator we-embedying4 theI invention and which has.` a pairof spacer plates` between each pair of' liquid` courses. Fig. l is an enlarged elevational View illustrating in detailgthe structure occurring at the junotions of the vertices of the fins and spacer plates shownr inFigs. 2 and 3.

the form shown in Fig. l, my improved' radiator core includes a series of spaced tortuous liquidcourses I and 2,4 of which only two are shown. These liquid courses each comprises a pair of. corrugatedplates 3 and 5 which have their longitudinal edge portions' 6 and 'I soldered together. The intermediate portions of; the plates 3 ,and 5 are offset outwardly with respect tof each other so as to provide a passage for conducting liquid cooling medium` irolnthe uppertank to the'lower tank of a'radiator. Integral ns 8 and 9 are formed on the plates 3 and 5, respectively, at. the vertices of the ridgesthereof. These ns extendvtransversely ofthe space between adjacent liquid courses.

A'corrugated spaced plate tvveeneach pair of adjacent liquid courses I and Z With thervertices of the ridgesv on opposite sides of the spacer plate contacting with the side edges ofv the fins of the adjacent liquid courses. Each ridge of the corrugated spacer plate I0 yincludes. a pair 'of converging panels or sidesfII on which are formed closed protuberances I2 that vextend into the air` Acells I ,3 adjacent thefliquid courses. Thesehexagonal cells Aare called liquid bound cells Aand' they are bounded on two sides by the plates of the liquidv courses. yand on two vopposite sides bythe vpanels of the spacer plate, and the remaining sides are provided by the iins of Athe liquid courses. l" f The protuberances I2, shown in Fig. 1, are preferably formed by pressing the metal of the panelsl of `the spacer plate I outwardly from theirv respective planes With the aid of suitable dies. These protuberancescof adjacent sides of a ridge fmay register with each other or they may be formed in staggered relation to Yeach other. In either event,l however, each of the adjacenty sides I5 of the opposite protuberances of one ridge is substantially in the plane of that panel of the ridge which is opposite from the panel out of which the p-rotuberance is formed, as indicated by the dot `and dash line 30 in Figi. This construction provides V-shaped notches which serve as aligning means forretaining the vertices of the ridges'and the side'edges cf the ns inl alignment with each other. The completely Aclosed protuberances produce turbulence in the ycells and they eliminate the Ynecessity ofv "lo, lis located beperforating the spacer plate or otherwise slitting the metal in order to align the vertices of its ridges with the ns of the liquid courses. Since each ridge of the respectively opposite sides of the spacer. platey I0 contacts with a fin of the liquid courses, it is necessary to provide a pro- `tuberance I2 on both sides of each of the panels of the spacer plate I0. I,

In the formshown in Fig. 2, the liquid courses I and 2 aresubstantially identica-l in construction to the liquid courses described in the dis-f cussion of the form of my invention .shownv in Fig. 1, and the parts thereof are correspondingly designated by the same numerals. Thespacer plate I4, whichis located betweenl the liquid` courses, shown in Fig. 2, is also corrugated, but

it is provided with protuberances I5` of arform which are entirely diii'erent'from those rshown in Fig. l. triangular in shape and they, extend substantiallyirom the vertexof one ridge of the spacer plate to the` vertex ofthe next ridge on .the other side of the spacer plate. These protuberances are arranged on the 'respectivelyopposite sides of the spacer plate I4 `in staggered relation v and each protuberance has an extremity I6 which 0. gated spacer plates I1 similar to the type shown 4 in my copending application, Serial No. 566,071, led September 30th, 1931, are disposed between` each pair of liquid courses-I and 2. The vertices of the adjacent ridges of these spacer plates contact with each other and provide an intermediate row of air bound cells I8 and the vertices of the ridges on the non-adjacent sides of the spacer plates II contact with the side edges of the fins 8 and!! of, the liquid courses. The side 50. faces or panels of the ridges of the spacer plates Il are provided' with alternate outwardly extending protuberances I9 and inwardly extending protuberances 20. The protuberances I9Y project into the4 liquid bound cells 2| adjacent the liquid courses and .the protuberancesZU project into the air bound cells I8,"producing turbulence in `the air flow through the respectivecells. The protuberances I9 extend beyond the vertices" of the corrugated spacer plates which contact with the fins 8 and 9 so as to properly align the` latter with the vertices of the'ridges. The extremities '22 of the protuberances 20 of one spacer plate which extend into the air bound cells I8 provide seats for receiving the ridges on the inner side ofthe other spacer plate. The extremities 22 of the protuberances 20 ralso extend beyond the vertices of theridges adjacent which they are located so as to align the ridges onadjacent sides of the spacer plates. with each other. l

In order to assure proper alignment of the fins of the liquid 'courses with the vertices at the outer ridges of the spacer plate I1 in both the forms shown in Figs. 1 and 3, the latter are 'provided with arcuate shaped grooves 23 in which the rounded ends 24 of the fins are received. With this construction, substantial contacting surface The protuberances I5 are generally...

is provided between the spacer plates and ns for the purpose of rapidly conducting heat from `the liquid courses to the spacer plates.

In each of the forms of the invention described above, the spacer plates are substantially imperforated and the vertices thereof contact continuously with the fins throughout substantially the entirelength thereof. The continuous contacting engagement. between the lns vand spacer plates permits solder to readily flow along sub- .;stantially the entire length of these parts, thereby producing metal to -metal attachment between the fins and spacer plates, which greatly increases the dissipation of heat from the liquid courses to the spacer plates by conduction.

Although but several specific embodiments of vthe invention are herein shown and described, it will be understood that various changes in the size,.:shape, and arrangement of parts may be made` without departing Afrom the spirit of the invention, and it is 4not* myintention to limit its scope other than by the terms of the lappended claims. f f Y `What I claim is: y, i 1,. `In a: radiator core structure, a pair of plates having edge portions sealed together. and spaced intermediate portions providing a liquid course, spaced Iinsextending routwardly from said liquid course, and an imperforated' corrugated spacer plate having the adjoining portions of the sides of its ridges contacting continuously with the side edges of said iins throughout substantially their entire lengths `and having closed` turbulence producing protuberances projecting from the sides of lsaid ridges beyond-the adjoining portions thereof and extending laterally of said sides Vof saidrldges throughout the major portions of their widths. j n
